      We present a numerical method for solving advective–diffusive–absorptive problems with high values of advection and absorption. A Lagrangian approach based on the updated version of the classical Particle Finite Element ...
    • Assessment of simplified momentum equations for free surface flows through rigid porous media 

      Düsterhöft Wriggers, Wibke; Larese De Tetto, Antonia; Oñate Ibáñez de Navarra, Eugenio; Rung, Thomas (Springer Nature, 2023-06)
      Article
      Accés obert
      In many applications, free surface flow through rigid porous media has to be modeled. Examples refer to coastal engineering applications as well as geotechnical or biomedical applications. Albeit the frequent applications, ...
    • Numerical prediction of the distribution of black carbon in a street canyon using a semi-Lagrangian finite element formulation 

      Puigferrat Pérez, Albert; Pouplana Sarda, Ignasi de; Amato, Fulvio; Oñate Ibáñez de Navarra, Eugenio (Elsevier, 2021-07)
      Article
